Le Cancer Metabolism Research Laboratory


Anne Le, M.D., M.Sc.

Primary Appointment in Pathology


My research is primarily focused on cancer metabolism, specifically studying the key enzymes of glycolysis and glutaminolysis: lactate dehydrogenase A and glutaminase. My research has shown that the inhibition of these enzymes induced oxidative stress thereby inhibiting tumor progression, demonstrating that targeting these metabolic processes can be used in the near future as a feasible cancer therapy. Using a Metabolomics approach, my laboratory is defining the factors that predict the sensitivity of pancreatic cancers to current chemotherapies and also to our novel small drug-like molecules. Our goal is to characterize and enable targeted selection of patients based upon predicted metabolic response. Furthermore in this pursuit, we have developed an innovative dual fluorescent protein reporter, termed HypoxCR, which can simultaneously detect cells that are hypoxic and/or cycling to study the effects of the tumor's microenvironment on the sensitivity to metabolic inhibitors.
